The Buffalo Bills have been in Orchard Park for the last three days, the first few days of the team’s five week Voluntary Offseason Conditioning program. And new Head Coach Doug Marrone has been using the first few days to get to know the returning veterans on the roster.Appearing on The John Murphy Show Thursday night, Marrone said the first few days of the offseason program have been spent in the fieldhouse for running drills, in the weight room, and in the meeting room. And he says some of the most important business being conducted this week is just the meet and greet with the vets.“At first, I want to make sure the players know how excited I am to be part of this organization,” Marrone said on the radio show. “I think it’s important that they see that and feel that. That’s been my big thing-energy. I think when you get to the situation right now, with the coaches all new, and some of the players are the same, but the chemistry of a team changes from year to year. You want to make sure you’re building that trust, the communication. You’re learning how to communicate and it takes some time.”Because Marrone takes over as a new coach in the NFL, he and his staff get a two week head start on their voluntary conditioning program over teams that did not change coaches. But as a former NFL players and assistant coach, Marrone says starting in early April really isn’t that early.“Whether it was four years ago when I was coaching in this league, or whether it was when I was a player-we always reported quite early,” Marrone told host John Murphy. “It gave us a lot of time to run, lift, condition, before we really ever started working in a minicamp with our coaches.”
